Knobs
| Control | MIDI CC | Description |
|---|---|---|
| INST VOL | CC 22 | Instrument channel gain. Slightly brighter and more aggressive as you turn it up. Ganged (jumped) with Mic Vol when both are turned up. As volume rises, the amp becomes more overdriven and compressed — authentic tweed behavior. |
| MIC VOL | CC 23 | Mic channel gain. Darker and cleaner than the Instrument channel, with more bottom end. Ganged (jumped) with Inst Vol when both are turned up. As volume rises, the amp becomes more overdriven and compressed. |
| OUTPUT | CC 7 | Post-amp output level. At noon (running direct or into other pedals), output is roughly the same as bypassed volume. Not a control on the original amp — added for practical pedalboard use. |
| ROOM | CC 30 | Amount of studio room ambience mixed into the signal. Fully off is like recording in an isolation booth; turning up adds ambience from the tracking-room mics. There is no fully-wet Room sound. Room has no effect when the cab is bypassed (No Cab) or in 4-cable mode — the Speaker LED blinks rapidly to indicate an inactive knob. |
| TONE | CC 31 | The amp's treble frequencies. Interactive with amp gain — as Tone is turned up, the pedal's overdrive and distortion increase. Start around noon for cleaner sounds, increase for more gain and brightness. This is the single tone control on the original 5E3 tweed circuit. |
| BOOST | CC 41 | Boost amount. Fully counter-clockwise (0) = OFF, no boost applied. As the knob is turned up, the selected boost circuit (KP-3K, Stock, or EP-III) adds gain and character to the amp's input. |
